To all who/m, may concern. W Be'itknownthat 1, JOHN K. STEWART, a "citizen of the United, States, residing at New York city, inthe county of New York and State of NewYork, have invented a new and useful Improvement in Automobile-En- .gine Stdftel"S,bf w ic -ea "followiiig is a specification,reference being had to the acdrawings, forming part thereof. p This application "is a division of my pending application, SeriaIlNof. 60,728, iiledNovember 10,1915. pp The purpose offthis invention is" to r-ovide an improied form of starter for the engine of an'a itomobile,tobe mounted upon the exti'emefcross-bain of the .aiitoinobile chassis or frame, requiring no further, support. It c'onsistsin the elements and features of construction shown and described, as indicated in the claims.

In,the,,drawings:- Figure 1 is a detail plan view of the forward end portion of the chassis orframeof an automobile having its engineequipped with a starting device embodying this invention.

Fig. 2 is a partly sectional side elevation of the same, section being made for a part of the fore-and-aft extent at a vertical axial plane. 2

Fig. 3 is a forward end elevation. Fig. 4 is a rear end elevation of the starter detached from the chassis frame.

The starting mechanism which constitutes this invention is shown in the drawings applied to a familiar type of motor vehicle by substitution of the mounting parts of the starter in the position and place of certain familiar parts of such motor vehicle and its engine, which parts will be referred to but not shown in the drawings.

In the drawings, A represents a portion of the chassis or frame structure of the ve hicle, A beingthe, forward transverse bar which is situated above the forward spring partly shown. at B. C is the fan pulley on the engine crank shaft, D.

In place of the bearing pillow for the forward and of the engine frame or crank case, E, and the journal bearing of the customary starting shaft, which pillow together with shaft and its crank connecting with its engine the present startingde'vice, there is mounted onthe forward transverse frame bar, A the starter casing, 1, having at the rear end a flange, 1"", fitted to the seat on the bar, A from which the starting shaft bearing pillow has been removed together with its crank. The flange, 1, has acapped seat, 1*, for the rear terminahe, of the engine frameor crank case, in place ofthe similar seat with which the removed pillow was provided. In the casing, 1, there is journa-led the starting shaft comprising a rear member, '2, which enters through,but does not require any bearing a piii," 3*, which customarily also secures the fanpulley to the engine crank-shaft; and

said clutch-pin being first withdrawn to admit the cup-shaped terminal, 3, into the annular cavity of the fan pulley and then replaced passing through the pin holes, 3*, in the terminal, 3, secures the latter, and there by the starting shaft member, 2, permanently to the fan pulley and thereby to the engine crank-shaft. The engine-connected starting shaft member, 2, has an axial bore in its rear end in which is lodged acoiled spring, 4, which reacts between the bottom of the bore and end of the engine crank shaft which is exposed at the center of the hub of the fan pulley for thrusting the shaft member, 2, forward at its sliding connection with the terminal, 3, for engaging and permitting disengagement of said shaft member and a winding member in the casing not herein shown, but fully shown and shaft member, 2, is steadied and kept axially alined with the engine shaft, preventing rattling which might otherwise occur at this connection which is necessarily somewhat loose to insure freedom of sliding of the shaft member, 2, in the terminal,

It will be observed that the construction described constitutes a starter which is adapted to be supported securely and firmly upon the extreme forward or rear frame bar longitudinally from its rear end seatmg on and bolted rigidly to the forward cross bar of the vehicle frame and serving as the sole support of the casing 011 the vehicle; a sleeve seated on said flange for pivotally'supporting the forward shaft bearing of the engine; startingshaft journaled in the casing and extending through said sleeve with space therein about the shaft for the forward shaft hearing; and meansfor coupling the starting shaft to the engine, shaft behind said shaft 7 bearing.

2. In combination with the engine, shaft and frame and vehicle frame, a starter comprising a casin havinga flange by which it is mounted rigidly on and overhungforward from the forward cross bar of the vehicle frame; means on said frame for pivotally mountingsthe engine frame by means of the forward shaft bearing thereof;

a starter shaft journaled solely in the casing and extending back through said engine shaft bearing, and means by which it engagesthe engine shaft rearward of said bearing. I

3. In combination with the vehicle frame and engine mounted thereon having a shaft thereof terminating forwardly; a coupling member on the forward end of said shaft; a starter casing mounted rigidly on the front cross bar of the vehicle frame forward of said shaft terminal; a starting shaft journaled in said casing and extending rearward across the front frame bar a oouplingmember slidably engaged with'the rear end of said shaft for rotation together therewith, said coupling member being loosely engaged with the coupling member on the engine shaft for rotation therewith; the shaft having an axial bore in the rear end, and a spring-pressed center pin longitudinally reciprocable in said'bore having the rear end cone-pointed the engine shaft having its forward vend centrally provided with a seat for the cone point for coecentering the starting shaftwith the engine shaft;

In testimony whereof, I have hereunto set my hand at Los 'Angeles, this 26th day of February, 1916.
